I had all four wisdom teeth taken out back in April. About four weeks after the extraction, I found what I thought was a bone spicule leftover from my wisdom tooth extraction in April. My family dentist even said it was a spicule and that I would probably need to get it ground down by my oral surgeon. It's basically shaped like a toenail on the bottom left side where my one tooth was taken out.

I saw my oral surgeon about a week ago. He said it's not a spicule, but a "ledge." He said it'll either absorb itself within 4-6 months, or make its way completely through my gums and cause "unspeakable pain." He was not comfortable taking it out, as he said it's pretty close to my nerve.

However, I can't find any literature on what a ledge actually is and I didn't fully understand his explanation. It has caused some pretty significant on-and-off discomfort. Could someone explain what it is?
